The coupling of spin and charge correlations in La2-xSrxCuO4
Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed... -
Neutron spectroscopy of V7M molecular nanomagnets
A large amount of contemporary research by both chemists and physicists is focused on exploiting the spin of electrons with the attempt of revolutionising the current technology... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Is there an incommensurate magnetic resonance in La2-xSrxCuO4?
Most optimally-doped high- Tc cuprate superconductors show a magnetic excitation (known as the 'resonance') at q=(pi,pi ) whose intensity increases sharply below Tc. This... -
The relationship between the pseudogap and magnetic excitations in La2-xSrxCuO4
This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the... -
Magnetic excitations at the critical pseudogap point, p=0.19, in La2-xSrxCuO4
We propose to measure the spin excitation spectrum in cuprate superconductor, La2-xSrxCuO4 (LSCO) at x=0.19. Our aim is to resolve the doping dependence of the 18 meV spin... -
Magnetic field controlled quantum criticality in La2-xSrxCuO4
The application of a magnetic field offers a unique way to control a quantum critical point in some systems. For underdoped high temperature cuprate superconductors (HTS),... -
The 400 meV excitation in LSCO and its doping dependence
Neutron scattering techniques at the time-of-flight spectrometers at ISIS have shown that there is a well defined excitation with an energy of about 400 meV in YBCO. A similar... -
The Structure of the High-Energy ¿Paramagnon¿ Excitations in La2-xSrxCuO4
A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most... -

Nano-Sized Effect on Magnetic Properties of La2CuO4
Nano-sized effect of ferromagnetic and antiferromagnetic materials has much attention in the recent years due to their unique properties. In the last beam time, we got 3 days to... -
Spin Excitations and "Hourglass" Dispersion in the Model High-Tc superconduct...
The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to... -
